17 '0 @ZZ whom t may concern.'

Be it known that I, FRTDOLF OLsoN, a citizen ofthe United States, and a resident of Brooklyn, county olf Kings, and State of New York, have invented certain new and useful Improvements in Column Molds, of which the following, togetherwith the accompanying drawings, is a specification.

This invention relates to apparatus for the Vcasting of columns vand structures of like character. g

The objects of theinvention are to provide a mold for this purpose which will be `adjustable for columns of ydifferent height, which willbe simple and substantial in construct-ion and which will be capable of being quickly assembled and disassembled.

These objects I have accomplished in part byconstructing the mold with longitudil nally extensible telescopic sections and by the provision of simple means by which saidv telescopic sections may be readily adjusted withV respect to each other. Other features relate to the manner in which the separable `parts ofthe mold sections aire held. inassembled relation and certain details of con-- struction.

' In the accompanying drawings, I have' from the true spirit and scope 'of the in-l vention' as defined in the appended claims. Figure 1 of these drawings is a partly sectional view illustrating the moldadjusted toa short column. f

' Figure- 2 is a similar viewV showing the mold adjusted for a longer column.

Figurev 3 is a plan view of the mold on an enlarged scale. l Y

Figures 4f, 5 and 6 areV cross sectional views taken substantially o-n the planes of the lines 1- 4, 5 5, 6 6 of Figure 2.

VFigure 7 is an enlarged detail view of the adjustable support for the head portion of the mold.` Y

Figure 8 is an enlarged detail view of the connection between the upper column section and the head 'section of thel mold.

Figuresv 9 and 10 are detail sectional views of the relatively staggered securing means for they separable parts of the vmold sections. L

The upright or column portion of the mold. comprises in the present disclosure an intermediate tubular mold section 12, and` upper and llower mold sections 13 .and 14, y

telescopically engaged in the opposite ends of the same. These mold sections are adjustably` secured together byL connections consisting in the illustration of the boltrods 15 engaged atene end with annular-outv E bent hooked portions 17 at theirl opposite ends adapted to be hooked into longitudinally spaced'openings 18 on the outstand-r ing ribs or flanges 19of the intermediate mold section. The boltsl are adjusted accordingy to this present disclosure by wing nuts 20 engaged with the ends of the bolts and having a bearing against the outstanding flanges 16.

In practice, vwhen thesections are set up, a rough adjustment is secured by engaging the hooked ends ofthe stay bolts 15 into thenearest openings in the outstanding ribs on the .intermediate section and then the wing nuts are turned tor effectthe final adjustment of the telescopically engaged mold sections. By providing" wing nuts at both .sides of the flanges or abut-A ments 16; it will be evident that'the bolts may be adjustedin both4 directions either to contract or expand the mold longitu; dinally.

"Io facilitate the'quick engagement of lthe connecting means, I have shown the flanges .16 as provided with bayonetl slots 2];a cut inward from the 'edges thereof to receivey the bolts 15. With this arrangement when the nuts are loosened or removed the bolts maybe quickly set in the bayonet slots and engaged with the proper holes in the anchorage ribs 19. i'

The cap or head portion of the mold is designated 21 and the same is shown se-` cured to the upper column section by means of abutting flanges 22, 23 onfsuch adjoining sections which are connected bythe bolts 24 which are shown as releasably engaged in the bayonet slots 25 vformed inthe edges of the abutting'flanges.-

Similarly the top 26 of the mold is shown secured to the ca'p'portion of the Vmoldfby the bolts 27v engaged in the bayonet slots 28 provided in 'the abutting .flanges 29.

1 The several mold sections are separable to l permit the mold being removed kfrom the in the present disclosure,of relatively shortV readilyv adjustablev Y Vlongitudinally to open the mold and said complete column. The Vcolumn sections are shown formed each in two parts Vhaving lthe edges thereof abutting, as indicated at 30. These edges'V are secured in this relation by the angle irons 3l, 32 fastened along the edge portions of the two parts and arranged as indicated inV Figure 9, so that the angle iron 3l on one part projects beyond the edge of the mold' part to which it is secured and Y provides a seat at '33 for the edgeofvthe other mold part which as indicated, projects beyond the base part of the angle iron which is secured to such other part. In assembling the sections, these joints are odset or staggeredas indicated in Figures l and 2, and as shown in Figures 9 and 10.

Suitable means are provided for clamping the flanges together, said means consisting bolts. 3ft provided with Wing nuts 35. Y.

In Figure 7, I have shown how the head of the mold may be adjusted and secured to vthe adjacent framing which is indicated at 36. This adjustment is secured by means of ay -Wedge 37 inserted between the framing and an angle brace 38 at the edge of the top portionfof the mold. When the proper ad-.

justment of theseparts is securedv they may Vbe ,fastened in such relation Vas by means of'l 'nails 39 or otherA suitable fastenings.

What Iclaim is: f .Y

l. A longitudinally extensible column mold l comprising an intermediate tubular mold section and tubular sections telescopically engaged .with the Vopposite Vend/portions of the same, an outstanding longitudinally eX- tending rib onthe intermediatesection pro! Y vided `with a series of' 'spaced shoulders,- Vabutr'nentson the end sections,\and links ad.- Yjustably' connected'between said abutments and selected shoulders on the rib for adjusting the relation between t-he intermediate mold section and the sections at the opposite endsof the same.

V2. A'longitudinally extensible column mold comprising telescopically Vengaged tubular mold sections, an external longitudinal flange on vone of said sections provided with a series of spaced shoulders, an abutment on the other section, Vand a link adjustably connect-k ed with said abutment atone end'and hav-v ing a hooked portion at its opposite end for engagement with different shoulders on the outstanding: flange. l

A longitudinally extensible column mold comprising an "intermediate Ytubular mold section, mold sections telescopically engaged Y l Y in opposite ends of said intermediatev section, Vexternallongitudinally extending ribs on the intermediate section providedv each with a series of openings, external flanges on the Y end mold sections, and bolts adjustably engaged with-said flanges and provided Vwith angular end portions for hooked engagement inthe openings in the ribs.

4. longitudinally extensible column mold comprising telescopically engaged tubular end and intermediate mold sections, each, of said mold sections being separable longitudinally into separate parts, means Vfor securingrthe separable parts of the mold .sections in assembled relation, external longitudinally extending ribs on one of the sections provided each with a series of openings, an external flange on the adjacent` section and bolts adjustably engaged with said flange and provided with angular end portions for hookedrengagement in the openings in the ribs. Y
